Some bacteria are suffocating sea stars, turning the animals to goo

Dermasterias imbricata

The mysterious culprit behind a deadly sea star disease is not an infection, as scientists once thought. Instead, multiple types of bacteria living within millimeters of sea stars’ skin deplete oxygen from the water and effectively suffocate the animals, researchers report January 6 in Frontiers in Microbiology. Such microbes thrive when there are high levels […]

Feast your eyes on this 50-million-year-old assassin bug and its exquisite genitalia

An anode-free zinc battery that could someday store renewable energy

Renewable energy sources, such as wind and solar power, could help decrease the world’s reliance on fossil fuels. But first, power companies need a safe, cost-effective way to store the energy for later use. Massive lithium-ion batteries can do the job, but they suffer from safety issues and limited lithium availability. Now, researchers reporting in […]
